Clondalkin Flexible Packaging Bury has developed new lidding solutions for capsules used in T.O by Lipton, a new tea machine developed by brand owner Unilever.
Designed as perforated lids, the solutions are made from alufoil and come in multiple sizes for different tea blends.
T.O by Lipton is capable of sensing the different lid sizes and adapt its settings accordingly.
The machine has been ‘designed for home’ and its prongs puncture the perforations on the lids.
The punctures then allow water to be injected through one side of the capsule, forcing the tea leaves out of the other side into the brewing chamber to infuse.
The variants of tea and infusion flavours can be differentiated by the colour of the lids.
Clondalkin Flexible Packaging Bury managing director John Chadwick said: "We needed to create lids of the highest quality, which were easily perforable by the machine, yet robust enough to protect the integrity of the capsule, including the aroma and freshness of the product inside.
"We also had to manufacture the lids to a very tightly controlled tolerance, as the exact position of the perforations determines the functionality of the machine and the brewing process.
"We also had to produce five different colours of material that could be totally immersed during the brewing process and be guaranteed safe for human consumption.
"To ensure this, our materials underwent a rigorous external testing and certification process at the Intertek chemical testing laboratory, in the Netherlands."
